摘要： In a trans-axle casing having an open end closed by a removable cover member secured thereto, a differential gear unit is rotatably supported at its side-journals by a pair of tapered roller bearings which are removably coupled within each cylindrical bore in a pair of axially spaced carrier portions of the casing. The carrier portions each are formed with a radial slit which extends inwardly from an upright seating face of the casing and opens into an annular groove in the cylindrical bore. A shim plate of substantially rectangular shape is inserted into each of the carrier portions through the radial slit and engaged at a semi-circular inner end thereof with the annular groove to retain each of the bearings in place by engagement therewith, the shim plate being formed in a predetermined length to be retained in place by engagement with the cover member of the casing at its outer end when it has been fully engaged at its inner end with the annular groove.

摘要： Disclosed herein is a transmission mechanism in a manual transmission which may eliminate unsmooth movement of the shift fork along the fork shaft during a shift operation so as to improve the feeling of shift-and-select operation. According to the present invention, the shift fork which is selected by the axial movement of the shift-and-select lever shaft is effective to move together with the fork shaft at substantially same speed by the rotation of the lever shaft. For this purpose, the fork shaft is axially movably mounted on the transmission casing and is connected to the lever shaft.

摘要： Disclosed is a transmission manipulation device for a transmission which is improved in eliminating abnormal circumferential wear of a shift fork due to pressure contact with the sleeve of a clutch mechanism incorporated in the transmission. The device has a shift and select lever shaft provided with a first retaining portion and a second retaining portion. The second retaining portion is engageable with the engaging portion of the first shift head only when a first retaining portion engages with the engaging portion of one of a plurality of shift forks on the lever shaft. When the shift and select lever shaft is rotated after axial movement against the resilient force of a resilient member, the second retaining portion is retained by the first shift head to prevent axial movement of the lever shaft due to the reactional force of the resilient member.

摘要： The application discloses a method of assembling gears, transmission shafts, fork shift shaft and associated component parts of a 5-speed transmission for a vehicle. The fifth-speed gear and the hub therefor are designed to be installed outside the end of the transmission case which is remote from the end thereof secured to a clutch housing. After first to fourth-speed gears and associated component parts are mounted on the transmission shafts which have already been mounted at their one ends to bearings mounted on the clutch housing, the transmission case is moved over the transmission shafts, the gears and the associated component parts thereof in such a manner that an open end of the transmission case is directed toward the clutch housing until the open end of the transmission case reaches the clutch housing and the other ends of the transmission shafts are inserted into and project through bearings mounted on the other end of the transmission case. After the transmission case is secured at its open end to the clutch housing, the fifth-speed gear and the associated hub are mounted on the projecting ends of the shafts. The fifth-speed gear and the projecting end portion of the associated transmission shaft are provided with internal and external splines for engagement with each other. A cylindrical first jig is threadably connected to the end extremity of the projecting end portion of the shaft. Thereafter, the fifth-speed gear is axially movably mounted on the first jig. An annular second jig is then positioned around the first jig and axially outwardly of the fifth-speed gear and forcibly urged by a mechanical or hydraulic device against the fifth-speed gear to press-fit the same onto the splined part of the projecting end portion of the output shaft while the first jig is caused to take up the reaction force generated during the press-fitting of the fifth-speed gear.
